I also have a tangerine that shuts down immediately on booting 8.6, likely due to the updated ROM. I think at least one blueberry here can boot 8.6, is it worth potentially sacrificing a clamshell to the flashrom cause :)

The 630 is a 68LC040. I don't think SpeedDoubler would help much!

quokkadb is another way to get USB keyboard/mouse working :) I have a CF/IDE in my 640, and dual boot between 7.5.x and 8.1. The two SIMM 630 (like my 640) can go to 52 MB: 32 + 16 + 4

This is a great use of the PIOs on the Pi Pico!

Perfect, thank you!

Native extended attributes are the best, easiest way to lose data when you back up files. Will there still be a way to disable this in 4.0?

Which side of OH are you on? I have some parts and experience with those (extremely flakey) motherboards here in Pittsburgh.

Even with USB audio, the audio doesn't work well. There is no volume control, so you have to use a volume control on the speakers, and hope that the USB device outputs high enough level. Mine doesn't quite, so I have to turn the powered speakers way up to like 3/4 to hear it, where on a normal...

I'd look forward to your demo, but I only have a 630, not a 5200. So you'll have to upload a video of it!

Marathon Infinity can use the Valkyrie to upscale a low res render to full screen, and the source code is available so you can look and see how it does it: http://infinitysource.bungie.org/

LC needs a VRAM upgrade to do 256 on a 640x480. Sadly, the upgrade makes its slow video even slower :(

I bought a repaired 68040RC40 from Herb Johnson. I don't know who he got to repair it, but there is someone out there who is able to do it.

I am not sitting in front of that machine right now, but yes I believe "Open ROM" is the wrong choice. Check the menus for something that offers to install a ROM into Multi Flasher. Once you do it you'll get two file pickers, and maybe also a warning dialog.

The Graphiccelerator UI is confusing. You need to pick a menu item to install the ROM, not open multiflasher. So double check that you’re actually getting the rom loaded into Multiflashsr

I have flashed two with Multiflasher on a G5 running Mac OS X. One a 32 MB PC card that already had a 128K rom chip, another one of those 64 MB ones that are on ebay for $25 or so. I had to put a bigger ROM chip on that last one, I got the part number from bbraun's radeon 7000 page.

I never had much success with the reduced ROMs. I bought some 128K rom chips and successfully replaced one on a 64 MB radeon 7000 a few weeks ago, and flashed the retail 226 ROM on it. I'm not running Mac OS X though. Looks just like the silver heatsink ones on the left side of your picture.

There is a very basic MacRoman <-> UTF-8 converter in one of my Marathon tools: https://github.com/treellama/atque/blob/master/ferro/macroman.cpp If your project is GPL you can use that directly. Depends on how much modern C++ support you have too, I suppose. If one or the other of those is...

In my case it was not an AppleTalk or AP issue, as I was only trying to use IP at the time. But, I could have been doing something wrong. If you get the Ethernet working, should be straightforward to switch the interface to the Wifi and try it!

I have had trouble getting bridge to work with the Raspberry Pi wifi, so YMMV. If you have trouble with it, try Ethernet before going too far debugging it.

Interesting, I wonder if this would also work for firmware updated clamshells, which can no longer run stock 8.6
